The Aggregate Crushing Value (ACV) Test Set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod. All parts of the apparatus are produced from galvanised steel.

TA-0630 and TA-0640 Test Sets are also used for the Ten Percent Fines Value (TFV) of aggregates according to BS 812:111.
